The chapter discusses the importance of breaking out of loops prematurely in Python, detailing how to implement this using 'break' statements in both 'for' and 'while' loops. It highlights the efficiency gained by stopping the loop once the desired condition is met. The chapter also introduces the 'else' clause associated with loops to determine whether a loop was terminated naturally or through a break statement.

What we have learnt
- Loops in Python can be exited prematurely using 'break'.
- An 'else' statement can be attached to loops to check if they terminated normally.
- Efficient searching can be achieved by stopping once the target value is found.
Key Concepts
-
Term: Break Statement
Definition: Allows exiting from a loop before it naturally finishes.
-
Term: Else Clause for Loops
Definition: Executed only if the loop terminated without hitting a break statement.
-
Term: While Loop
Definition: A loop that runs as long as a specified condition is true.
-
Term: For Loop
Definition: A loop that iterates over elements of a sequence such as a list.
